For your amusement, the Babelfish [ babelfish.altavista.com ] version. Bummer about "the missing jumping screen" (g). Walter_E_Sch?/a > (member) 20/02/2005 17:01 Test in ColorFoto 5/1980, S. 48-58 In and 80's 70's I had tested 14 years long f?die magazine ColorFoto monthly a selection of Kleinbild SLR objectives. In number 4/80 and 5/80 were mirror lens objectives with focal lengths around 500 mm to. In second part of this test in number 5/80 I had along-tested some differently conceived lens objectives of this focal length range to the comparison also, (at that time) the very expensive Leica Telyt r 6.8/560 mm, which often used Novoflex Noflexar 8/600 mm with Schnellschu?andgriff (autofocus gab's 1980 not yet!) by animal photographers, the very bright Pentax SMC 4.5/500 mm and the comparatively mockery-cheap Beroflex 8/500 mm, only approx.. 200 DM, with Discountern even only approx.. 179 DM cost. The two first mentioned (Leica, Novoflex) were long-focus achromatic objectives, the two different were Telekonstruktionen with integrated Barlowelement. The result was, da?das cheap Beroflex not only relative to its low price very well cut off, but. apart from the smaller Lichtst?e and the missing jumping screen. in the total field very well to maintain ground could. Therefore I had written among other things at that time in the result: > > the Beroflex objective is characterised by a price achievement Verh?nis, which does not also only reach other objective of the test ann?rnd. It is compared with the Spiegellinsern a lange T?., but regarding its Bildqualit?und under Ber?sichtigung of the low price it earned rather the designation Wundert?.. < < The company Beroflex quoted this last sentence from my test then for many years in its advertisement f?dieses objective, and like that this objective under the name is Wundert?. popul?geworden. At that time very good cutting off may not do however to the Schlu?f?en, it is a just as good telescope objective! Schlie?ich was it as small picture objective f?einen picture circle of approx.. 43 mm konzipert, mu?also much gro?s an image field distinguish, how the Aufl?ngsverm?n also at the R?ern still f?Aufnahmen on film well its mu? in the center however by any means the Anspr?e of diffraction limited optics to erf?en does not have, as one expects it from a telescope objective. One can say in other words: In the image field center after Astroma?t?n Zugest?nisse were made, in order to erm?ichen in the boundary region f?gute photo photographs a sufficient Aufl?ng. F?Astrozwecke k?te itself I its employment thus in connection with 2"-Okularen f?gro? Visual fields with lower Vergr?rungen very well present, just as f?Astrofotografie (so far the small?fnungsverh?nis of 1:8 does not st?, for instance with the moon and much brightens other objects). With very strong Vergr?rungen with kuzbrennweitigen eyepieces it becomes probably entt?chen m?en. Walter E. Sch?
